I was pretty lazy regarding my pool over the winter, which is now upsetting me quite a bit. However, instead of crying about it I will post here, cry some more, and then get to work on turning this around! I ran my first full set of tests in many months. One thing I really don't understand is how my CYA dropped significantly: I do feel like today's reading was the most accurate I've gotten on the CYA though.
FC: 5 = I put a full gallon in before I left for work in the morning. That was at 8:30AM and I got this reading at 1:00PM
pH: 8.4 = That's a guess since it is darker than the 8.2 color on my tester
TA: 110 = This is consistent with what I was getting last year
CH: 450 = This is consistent with what I was getting last year
CYA: 30 = I ran the test twice but I had to reuse the test liquid; I have to reorder R-0013 so that I can verify this is accurate because last year I was getting from 90 to 110. The only water added has been a few inches from the very little rainfall we've had in SoCal.
Temp at the time of testing: 73F
I've been able to brush off the yellowish/green algae (?) on the sides but I am starting to notice brown spots on the stairs. I saw another post that said rub vitamin C tablets on those... Other than keeping my numbers in line, and verifying the CYA, what else should I be doing? The pool is clear after my Dolphin runs a cycle so it hasn't turned into a green swamp, I should have taken a picture, but do I need a shock treatment?
Thanks for any answers/pointers!
